I have been trying to document the correct procedure for adjusting the tracking based on the picture below from the manual. It states to adjust the linkage rods "A" and linkage rods "D". It does not however define which way to adjust them.
From my experience the following seems to be correct. I am hoping that someone can confirm this:

More questions:
Is there any reason to adjust the lower blade versus the higher blade or vice versa?
Does adjusting the tracking change the original swashplate leveling settings and or the original zero pitch settings during initial setup?

I put a mark on the grip and on the blade so they stay matched up if I have to disassemble for any reason. I then just make the adjustment for tracking on the marked side of the head. If blades are out of track....I make a change to the marked side. Choose to increase or decrease pitch....just pick one....if tracking gets better keep adjusting in that direction. If it got worse. Go the other way.

Simple and works. As long as I have a good background to see. Normally takes a one to four changes to have 'razor' edged tracking. Your ears will also learn to hear when it is correct. (head speed increases a little and blade sound gets crisp....especially with carbons.)

Take the time to get them right. It makes a big difference in performace.

I found that trying to adjust the tracking of the blades by "trial and error" usually takes more time than is worth it. I bust out my pitch gauge and adjust till both blades show 0 pitch at mid-stick in throttle hold (linear pitch curve). Then they're both perfect, and when I spin it up after replacing the blades TADAW! perfect tracking.

I love perfectly tracked blades.

Makes me feel confident.

Other than that, my little thing for adjusting the lengths is "L for lower, R for rise" as in left turn = lowers the pitch, right turn = raise the pitch. Of that one particular blade of course.
